Trying to buy from Trapstar London

So i'm trying to buy a few tracksuits to re-sell from Trapstar London today, its very common knowledge that everything on their website sells out within a few seconds of them stocking (probably because of bots). But is there a good way to buy from a shop like this? or is it just luck? Also at what point in the checkout process would they reserve the item for you? Im assuming you don't have to put in all your card details and address before you actually reserve the item because then it would just be bots that get everything. If anyone has any advice/information on how to buy it would be greatly appreciated via /r/streetwear https://ift.tt/3la1eJu
